I have a small LVM setup at home, consisting of 4 partitions. These were created by the Mandrake 8.2 installation system. After deciding to upgrade the system to Mandrake 9.0, I found out that I had another partition lying around which was also prepared for LVM use. I had meant for that disc to use later on in a different scheme for my /usr partition but never got around to do it. However, during installation I decided to add it to the LVM. The idea was that I would extend the FS later (of course, I was not going to involve this LVM setup in the rest of the installation, I would do all that manually.) But as you probably guessed, something went horribly wrong during install time and my LVM setup is properly hosed. I wanted to re-create the setup, but alas: I forgot which was the disk that I added. The name of the LV (there was only 1) was home, the disks involved were /dev/hda1, /dev/hda[4-6].
